Studies on some volatile flavour constituents in orthodox black teas of various clones and flushes in North‐east India

Abstract

Abstract Volatile flavour constituents (VFC) of orthodox black teas manufactured from various cultivars of different geographical areas were analysed by gas chromatography and mass spectrometry. Well marked variations in VFC, as observed, were due to differences in weather conditions during the growth periods and manufacturing techniques. In general, second flush teas contained a higher amount of monoterpenoids such as linalool, their oxides and geraniol compared to rain flush teas of both low grown and high grown areas. Non‐terpenoid products such as hexanol, z‐3 hexenol, benzaldehyde and benzyl alcohol were higher in rain flush teas than in second flush teas of only high grown areas.
